Prostate-specific antigen (PSA) is a protein produced exclusively by prostate cells. There is a simple blood test to measure your PSA level and this may help to detect early prostate cancer. The chance of having prostate cancer goes up as your PSA level increases (see table below). Small ...
PROSTATE-specific membrane antigenObjective: The aim of this study was to detect a prostate specific antigen (PSA) cut-off value for metastases, and prevent unnecessary use of Ga-68 prostate specific membrane antigen (PSMA) ligand positron emission tomography/computer...
Prostate-specific antigen (PSA) test.This blood test checks the amount of a protein calledPSA,which is produced by prostate cells. Higher levels may be a sign of cancer. By themselves, they are not proof you have prostate cancer. Higher levels could also point to an enlarged prostate or pr...
Prostate-specific antigen (PSA), is a protein produced exclusively by the male prostate gland. It is a normal secretion of the cells of a healthy gland. The PSA test measures the level of this antigen in a blood sample. Doctors will often order a Prostate Specific Antigen (PSA) test to ...
You may be familiar with a screening blood test called PSA, or prostate specific antigen. There are limitations to using PSA testing to screen for prostate cancer, since this protein is made by both BPH (an enlarged prostate) and cancerous prostate tissue. Since both BPH and prostate cancer...
Prostate-specific antigen (PSA) levels are markers for prostate cancer. With biochemical recurrence (BCR), “prostate cancer has come back in the form of a PSA rise by itself, but the cancer is not visible on any imaging,” explains oncologist Rana R. McKay, M.D., associate professor of...
Prostate-specific antigen (PSA) blood test. HighPSAlevels may be a sign of a larger-than-usual prostate. A doctor can also order it as a screening test for prostate cancer. Advanced tests Based on the results of those tests, your doctor may order more tests to rule out other problems or...
PSA Tests The prostate gland produces a protein called prostate specific antigen (PSA). Most of the PSA is removed from the body with semen, but some of it ends up in the bloodstream. Normally, this is a very small amount that is either free floating or bound to other substances. ...
Prostate specific antigen (PSA) continues to be challenged as a legitimate clinical biomarker in early detection of prostate cancer due to lack of specificity for malignant transformation. Skepticism surrounding the utility of serum PSA as a clinical marker is not new and many questioned its initial...
Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated. However, PSA levels can spike in noncancerous conditions, such as ...
